Answer:

D. 160

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

In this question:

For each 3 white carnations, 5 yellows are needed, which leaves us with 8 total carnations. So for 60 white, the total is:

3 white - 8 total

60 white - x total

$3x = 60*8$

Dividing both sides by 3

$x = 20*8 = 160$

The correct answer is given by option D.

Answer: $1590cm^3$

Step-by-step explanation:

$V=\frac{3\sqrt{3} }{2}a^2h$

a = base

h = height

$V=\frac{3\sqrt{3} }{2}(6cm)^2(17cm)$

Solve the parentheses squared first.

$V=\frac{3\sqrt{3} }{2}(36cm^2)(17cm)$

2 and 36 can be simplied

2/2=1

36/2=18

$V=3\sqrt{3}(18cm^2)(17cm)$

$V=3\sqrt{3}(306cm^3)\\ V=1590.02cm^3$

Rounded to the nearest whole number... $1590cm^3$
